ABSTRACT
The history of mankind from the early days of civilization has been bound up with animals. At the more advanced levels of societies in the developed countries, it is recognized that animal products indicate a higher standard of living, not only nutritionally but also as more general indicators of wealth. Eggs are another food product of animal agriculture; the great majority is produced by the chicken, with turkey, guinea fowl, duck, goose, and plovers contributing relatively few. Management is perhaps the key to the conservation program, which seeks to conserve animal genetic resources by using them for food, fiber, and work. The process of teaching people who have never kept animals before usually involves a fundamental change in their lifestyle and eating habits. Assisance is relatively easier when the community already keeps animals, and improvement is thus primarily a matter of modifying the technique or system or genetic resource in some way.
